| Zusammenfassung |
| Tectonomagnetic field observations from absolute magnetic field levels have
been collected in Central Italy since 1989 by means of a network of four
absolute magnetometer stations, including the geomagnetic observatory of
L'Aquila (42°23 N, 13°19 E) used as reference for
differentiation; also electromagnetic variations from VLF signals have been
recorded in the last years by means of VLF search coil wide-band antennas.
Many reports proved the occurrence of electromagnetic effects clearly
related to tectonic events (seismic and volcanic activity) in active areas
of our planet. In this paper we show the variation of some electromagnetic
parameters which could be related to local and regional seismic activity for
the most recent years 2002 and 2003. We also report the seismic activity
recorded in this area by the Italian seismic national network.
Some tentative analysis (in the wavelets and statistical approach) on the
historical and recent dataset allow a better characterization of
electromagnetic properties of the study area, at different temporal and
spatial scales. |
